proposed api change
Counting of visible parents in Autoupdate UI is very expensive, finding for visible parents in Autoupdate Services can work smoothly. I proposed to add new methods to UpdateUnit which returns a visible ancestor of UpdateUnit if any. Autoupdate UI will use it instead of complex searching.
Thanks for review.
